Welcome to the
Air Quality Division

DEQ is now accepting applications for the 2017 Oklahoma Clean Diesel Grant Program. $566,018 is available for replacement and idle reduction projects for school buses and similar vehicles. Applications will be accepted until January 19, 2018.

The annual emissions inventory workshop, including a presentation on E-permitting, is scheduled for January 23 at the National Weather Center in Norman and again on January 31 at the OU Schusterman Center in Tulsa.

AQD's Permitting group has posted new guidance to estimate condensate and crude oil loading losses from tank trucks. The guidance is in response to requests for alternative emission factors in some proposed permit applications.

What is air quality?
The amount of pollution in the air from all sources - natural and human - defines the quality of the air we breathe. Air pollution isn't limited to our cities; it can blow into any part of Oklahoma from neighboring states.

Why is it important?
Bad air quality can affect everybody's health. It can have direct effects on the lungs, and it can worsen an existing condition, such as asthma. Some people are more sensitive to air pollution than others. These include young children who are growing rapidly and older adults who have reduced immune systems.

Poor public health also incurs economic costs for society, e.g., increased healthcare costs and loss of working days. And a clean environment makes Oklahoma an attractive place to live, work and play: something we can all be proud of.

What does the Air Quality Division do?
Most importantly, we work to effectively protect the public health in Oklahoma. We do this by:

Implementing the state and federal Clean Air Acts to reduce emissions and improve air quality in Oklahoma. AQD recommends adoption of Air Quality Rules and operates regulatory programs that realistically balance the needs of all the state's stakeholders.
